inconsistent usage of CLI flags

[igable]

There are cases where different commands use --server_id , --serverid, and --server-id . We should follow GNU conventions on CLI flags i.e. no underscores.

In cases where the command operates on ID for a particular object that the id should be dropped from the the flag name. For examples:

dcm-terminate-server --server_id 2 ➡️ dcm-terminate-server --id 2

The old flags would be kept in place and marked as deprecated until Mixcoatl 2.0
